About Circeus

Circeus is an AI-native holding company that acquires and evolves mission-critical B2B software businesses globally. We serve 200,000+ businesses worldwide, focusing on the vertical and workflow software the everyday economy runs on.

Our model is direct: acquire strong software businesses and evolve them through a centralised AI platform, driving both revenue growth and operational efficiency. We operate as long-term owners, not flippers, continuously improving every product through applied AI.

The Role

We’re hiring a Founder Associate to work directly with the CEO across the highest-priority initiatives at Circeus. This is a front-row seat to how an AI-native holding company is built and scaled, spanning fundraising, investor relations, market research, and strategic projects that don’t yet have an obvious owner.

You’ll move between deep analytical work and fast-turnaround execution, often on the same day. One week might mean prepping investor materials, the next researching a new vertical or acting as the connective layer between the CEO and AI tools that speed up decision-making.

This suits someone entry-level who wants exposure to company-building at pace, not a structured graduate scheme. You’ll be trusted with real scope quickly, and the CEO will expect you to bring structure to ambiguity rather than wait for it.

What You’ll Do

• Support fundraising processes, including materials, data rooms, and diligence coordination
• Maintain and strengthen investor relationships alongside the CEO
• Conduct market research to inform acquisition targets and strategic direction
• Act as an AI intermediary, using AI tools to accelerate the CEO’s decision-making and output
• Prepare briefing documents, board materials, and strategic memos
• Track and follow up on action items from CEO meetings and investor conversations
• Synthesise research into clear recommendations for the CEO
• Coordinate across portfolio companies on CEO-led initiatives

What We’re Looking For

• Strong academic record with clear evidence of analytical rigour
• Excellent written and verbal communication skills
• Comfort working directly with senior stakeholders and investors
• Genuine curiosity about AI tools and how they can accelerate individual output
• Ability to context-switch between strategic and administrative work without losing quality
• High ownership mentality and comfort operating with limited structure

Nice to Have

• Prior internship in venture capital, private equity, investment banking, or a startup
• Experience with fundraising materials or investor communications
• Exposure to SaaS or B2B software businesses
• Familiarity with AI tools such as Claude, ChatGPT, or similar for research and productivity

Why Circeus

• Direct, sustained exposure to a CEO building an AI-native holding company
• Visibility across a portfolio of 200,000+ served businesses, not a single product
• Real ownership and pace from day one, not a rotational graduate programme
• Access to a centralised AI platform used to drive measurable impact across the business
• Competitive compensation with genuine growth trajectory for high performers

If you're excited by high ownership, steep learning curves, and the opportunity to help build an AI-native software holding company from the inside, we'd love to hear from you.
